• Create a new ScriptStoreSQLite object for script and value persistence, or implement your own ScriptStore.
• Make the WebView class that you want to run scripts in extend WebViewGm, or use the ScriptBrowser class in the UI module.
• Handle the management of scripts using the classes in the UI module, or extend them, or implement your own.

The demo module contains an implementation of the library and all its components. It uses a single WebView for both the download of user scripts and running them.
